ResearchEvidence-basedEducational
The evidence for cannabis varies enormously by health condition, from well-supported to barely studied, and these pages summarise it condition by condition, grouped by how strong it is. It is educational, not medical advice.
Best-supported uses
Where high-quality reviews (such as the 2017 National Academies report) found substantial or conclusive evidence, or where regulators have approved cannabis-based medicines.
Emerging and mixed evidence
Where some studies are promising but the evidence is limited, mixed, or mostly preclinical. Treat claims here with caution.
Important. This page is educational and is not medical advice. Cannabis is not suitable for everyone, can interact with medications, and the strength of evidence varies by condition. Talk to a qualified healthcare professional before using cannabis for any health condition.
